Biography
Oda Nagamasu (織田 長益), also known by his artistic name Yūraku or Urakusai, was born in 1548 in Owari Province, Japan. He was the younger brother of Oda Nobunaga, a powerful warlord and key figure of the Sengoku period. This family tie put Nagamasu at the center of major military and political events in 16th-century Japan, although he eventually made his mark more through cultural and artistic pursuits than military success alone.
Nagamasu took part in several military campaigns during the turbulent Sengoku period, serving under his brother Nobunaga, and later navigating the tricky political times after Nobunaga was assassinated at Honnō-ji in 1582. His actions at the Battle of Sekigahara in 1600 drew criticism from some, as it is said he pulled back from the battle at a crucial moment. Despite this, he gained favor with the Tokugawa clan and was given a domain of 30,000 koku in Yamato Province, becoming a daimyo under the new Tokugawa shogunate.
In 1588, Nagamasu converted to Christianity and took the baptismal name John, joining many Japanese nobles and daimyo who adopted Catholicism after contact with Jesuit missionaries. His conversion was part of a larger, though short-lived, interest in Christianity among Japan's elite during the late 1500s. As the Tokugawa regime took hold, Christianity faced growing suppression, and Nagamasu's public connection to the faith faded as a result.
In addition to his political and religious life, Nagamasu gained lasting fame as a master of the Japanese tea ceremony. He studied under the renowned tea master Sen no Rikyū and became one of the top practitioners of his time. His tea style, linked to the Urakusai school, had a lasting impact on the art form. He designed and built the Joan tea house, a small yet beautifully crafted structure now designated a National Treasure of Japan. Nagamasu spent his later years in Kyoto, where he continued to refine his artistic practice until his death on January 24, 1622.
Before Fame
Oda Nagamasu was born in 1548 in Owari Province, a central region in Japan that later became the starting point for his brother Nobunaga's rise to national power. Growing up within the Oda clan during a time of frequent territorial wars, Nagamasu was influenced by an environment where political survival relied on both military readiness and smart alliance-building. Being close to one of Japan's most ambitious leaders gave him early exposure to power and strategy.
As Nobunaga's younger brother, Nagamasu held an influential yet secondary role. This may have led him to focus on cultural refinement, especially the tea ceremony, which was not only an art but also a key area for political diplomacy and social prestige at the time. Studying under Sen no Rikyū, the leading tea master of the era, placed him among Japan's cultural elite and set the stage for his later recognition as a respected artist and tea practitioner.
